Really at the end of my wits, onboard NIC won't function with a Realtek NIC installed in the Legacy PCI slot.
I need two NIC's operating for a specific function and I dread having to buy another $260 motherboard just for this task.
I have updated to the latest current BIOS firmware, to no effect.
I have disabled all other devices onboard, to no effect.
The restricted and limited BIOS design also refuses to allow me to forcibly move the onboard NIC onto a different IRQ address, which I suspect is the problem.
Please advise me on what to do, I have the Serial Number & AA number available.
